I think my complaint with the character models mostly deals with how bad the faces animate, but her radical style change doesn't help, either. She looks all right when she shuts up, but... guh.

That video is a bad example of facial animations and pretty much everything else. At 20 seconds a character is frozen in place between Anderson and Shepard for several seconds before blinking out of existence. I don't like to use the "it's just a demo" excuse but after seeing that I think it's pretty clear they still have some things to correct. Facial animations might be one of them. Also, something about the running animation in the playable demo is hilariously awkward.
